Based on the sample proportion, how many students in the school would be expected to play indoor games for at least four hours every week? 546 598 702 1,248

Question

Answer:

You could expect about 1,248 students to play at least 4 hours every week.

Our tables have 100 students involved. All but 4 of the students are in the category of at least 4 hours. That is 96%.

Therefore, we simply need to multiply 0.96 by 1300 to get the estimated amount.

0.96 x 1300 = 1248
